Definitions

the present invention relates to an agricultural wire-tensioning element, to a device or elastic compensating element comprising said element and a system for supporting rows of plants including such wire tensioning element.
the invention relates to a wire tensioning roller provided with a structure that is advantageously adapted to separately adjust the tension of two wires.
connection wires are commonly referred to as “containment wires” or “movable wires” given that, during the various stages of plant cultivation, they are moved to different heights from the ground to contain and organise the growing vegetation according to a desired configuration.
movable wires are arranged close to the ground.
each pair of movable wires is placed progressively further away from the ground in the direction orthogonal to the ground, harnessing the vegetation between the wires of each pair, therefore organising the development thereof according to a desired configuration.
This operation is commonly carried out to ensure an increasing exposure of the foliar surface and the fruits of the plants to the sun and wind. Furthermore, this facilitates vegetation treatment operations such as clipping, plant protection treatments and other fully conventional treatments.
rollers In particular, the tensioning of fixed or movable wires is carried out by means of tensioning elements or wire tensioners generally represented by rollers.
These rollers shall consist of a rod with a cylindrical cross-section and/or at least partly solid or hollow polygonal and provided with transversal holes for engagement with one or more ends of metal wires to be tensioned.
transversal holes for engagement with one or more ends of metal wires to be tensioned.
rollers have been used for a long time and are usually associated with a head post, as described for example in the patent application WO2007060225 , or combined with elastically compensating devices, as described in patent EP1699286 .
the task of the present invention is to provide a wire tensioning element or roller that avoids the aforementioned risk of misalignment of the two wires tensioned differently.
an object of the present invention is therefore to provide a wire tensioning element with a structure which allows to separately adjust the tension of the two wires.
a further object is to provide a wire tensioning element that is easy to use for adjusting the individual tension of the wires.
a further object is to provide an elastically compensating device comprising the aforementioned wire tensioning element, as well as a system for supporting rows of plants comprising the aforementioned wire tensioning element.
Figure 1A shows a wire tensioning element 1, according to the present invention, formed by two portions, first 2 and second 3, which can be assembled together along a common rectilinear axis X-X.
the first portion 2 is generally cylindrical bar-shaped comprising a first end 20 and a second end 21 opposite the first.
the first end 20 is provided with means 22 for engagement with a tool (not shown) for driving the first portion in rotation around the axis X-X.
a tool not shown
such means are a hexagonal surface which can be engaged by a corresponding hollow hexagon head tightening wrench.
the engagement means may be a through hole which can be engaged by a rod, such as the shank of a screwdriver.
the first portion 2 comprises a through hole 23 for engagement with an end segment of a wire to be tensioned, as explained below.
the second end 21 is a pin which extends axially and represents a first means for engagement with a complementary second engagement means obtained on the second portion 3, as described below.
the pin 21 has a radial extension that is smaller than the rest of the first portion 2 so as to create a radial ring 24.
such ring 24 shall be serrated and shaped so as to cooperate with a corresponding complementary serrated ring entirely obtained on the second portion 3, so as to allow the rotation of each of the portions, first 2 and second 3 around the axis X-X only in one direction, clockwise or counter-clockwise, this however preventing the mutual rotation in the opposite direction, counter-clockwise or clockwise. Therefore, the two serrated rings of the respective first 2 and second 3 portions of the roller 1 face for an axial engagement, as explained in greater detail below.
teeth 25 of the ring 24 are radially inclined in a single direction to form a ring in which there are alternated a shoulder 25A of a tooth and a ramp 25B of an adjacent tooth.
the teeth are inclined with respect to the direction orthogonal to the axis X-X.
the number of teeth may vary depending on particular needs or preferences. Preferably, there are six of them, they have a radial extension of 60° and a 5°-40° degree of inclination with respect to the X-X axis.
the radial surface 26 of the teeth 25 extends axially towards the first end 20 with a polygonal shape, preferably hexagonal, followed by an annular seat 27 for engagement with a portion of an elastically compensating device, as explained below, or with the edge of a hole of a post (not shown) for supporting a row of plants.
This seat enables the roller 1 of the invention to be rotatably supported on said elastically compensating device or on said support post, when provided for.
the second portion 3 of the roller 1, as shown in figure 1B has a shape generally identical to that of the first portion 2, with a first end 30 and a second end 31.
the first end 30 is provided with means 32 for engagement with a tool (not shown) for driving the second portion in rotation around the axis X-X.
a tool not shown
such means are a hexagonal surface which can be engaged by a corresponding hollow hexagon head tightening wrench.
the means may be a through hole which can be engaged by a rod, such as the shank of a screwdriver.
the second portion 3 comprises a through hole 33 for engagement with an end segment of a wire to be tensioned, as explained below.
the second end 31 comprises a cylindrical cavity 34 which is axially open and with a closed bottom which extends axially and represents a second means for engagement with the aforementioned first complementary engagement means represented by the pin 21 of the second end of the first portion 2.
cavity 34 has a serrated annular radial edge 35 which surrounds the opening of the cavity.
the teeth 36 of the annular edge are arranged in a mirror-like fashion with respect to the teeth 25 of the annular radial ring 24 of the first portion 2. Therefore, also these teeth 36, preferably are radially inclined in a single direction to form a ring in which there are alternated a shoulder 36A of a tooth and a ramp 36B of an adjacent tooth.
the teeth are inclined with respect to the direction orthogonal to the axis X-X.
the number of teeth may vary depending on particular needs or preferences. Preferably, there are six of them, they have a radial extension of 60° and a 5°-40° degree of inclination with respect to the X-X axis.
the radial surface 37 of the teeth 36 extends axially towards the first end 30 with a polygonal shape, preferably hexagonal, followed by an annular seat 38 for engagement with the edge of a hole of a post (not shown) for supporting a row of plants.
Said seat allows the roller 1 of the invention to be rotatably supported by a support post, when provided for, also at its second portion 3 for greater stability.
the two portions are assembled by inserting the pin 21 of the first portion into cavity 34 of the second portion so that the annular step 24 and the radial edge 35 come into contact with the ramps and shoulders of the respective teeth in complementary contact.
figure 3 shows an elastically compensating device 100 or damper comprising the tensioning element 1 described above.
the elastically compensating device 100 is substantially a device like the one described for example in patent EP 1699286 and it comprises an elastic element 5 which extends along a rectilinear axis Z-Z between a first 6 and a second 7 hook-like element.
the elastic element 5 is preferably a compressible spring between said first 6 and second 7 hook-like elements, which extends between a first 50 and a second 51 end.
the first hook-like element 6 comprises a first end 60 for fixing to a post (not shown) of a row head, a second end 61 for retaining the second end 51 of the elastic element 5 and a straight section 62 which connects said ends and it is such to be inserted into the internal space defined by said elastic element.
said first hook-like element is formed by a metal wire folded to form a U shape in which the first end 60 protrudes from the first end 50 of the elastic element 5, it is closed and variously shaped to be connected directly around said post or indirectly using a collar or further connection means such as for example a chain, or using a screw transversal to the post.
the second end 61 of said first hook-like element comprises two portions of wire 63 which are folded divergently so as to create two hooks for engagement with at least one turn of said second end 51 of the elastic element.
the second hook-like element 7 comprises a first end 70 for supporting the wire tensioning element 1 of the invention, a second end 71 for retaining the first end 50 of the elastic element 5 and a straight section 72 between said first and second end adapted to be inserted into the internal space defined by said elastic element.
said second hook-like element is formed by a metal wire folded to form a U shape in which the first end 70 forms two parallel foldings 73 each for engagement with an annular seat 27, 38 respectively of the first 2 and second 3 portion of the wire tensioning element 1.
the second end 71 comprises two portions 74 (only one visible in figure 3 ) of a wire folded divergently so as to create two hooks for engagement with at least one turn of said first end 50 of the elastic element 5.
the wire tensioning element 1 is fitted, for example, to the first end 70 for supporting the second hook-like element 7 of an elastically compensating device 100 so that the parallel foldings 73 each engage a seat 27, 38 respectively of the first portion 2 and of the second portion 3 of the wire tensioning element ( figure 3 ).
a metal wire (and not only, for example also plastic) W is inserted into each through hole 23, 33 respectively of the first 2 and second 3 portion.
one of the two portions of the wire tensioning element 1 is driven in rotation by engaging with an appropriate tool (not shown) which acts on the first end 30 thereof.
an appropriate tool (not shown) which acts on the first end 30 thereof.
the engagement described above allows to wind the wire W on the second portion, leaving the first portion 2 still, preferably held still using a further tool which engages the first end 20 thereof, for greater safety, bringing the wire to the desired tension.
the first end 20 of the first portion 2 can be adjusted to wind and therefore tension another wire W thereon ( figure 4C ).
the rotation occurs is in the opposite direction with respect to the rotation direction of the second portion 3.
the wire tensioning element 1 of the invention is mounted on the aforementioned elastically compensating device 100 so that, during the tensioning of the wires ( figures 4B and 4C ), the elastic element 5 is partially compressed.
this completely conventional operation can be carried out separately for the two wires so as to adjust not only the tension individually but also as a result any asymmetries which can easily appear between the two wires W.
the wire tensioning element 1 may be arranged inclined with respect to the longitudinal extension of the wires W, both on the vertical and horizontal plane.
the elastic element 5 of the elastically compensating device 100 could easily twist with greater shortening of the turns on one side with respect to the other and, therefore, negatively affect its correct functionality.
the wire tensioning element 1 can be mounted, for example, directly on a support post thanks to the engagement between the edges of two holes on opposite walls and the two circular seats 27 and 38 respectively of the first 2 and second 3 portion.
figure 5 schematically shows a system 11 for supporting the vegetation of a fruit-bearing plants-row, preferably for a vineyard, comprising two head posts P fixed into the ground with suitable fixing means F known in the industry, such as tensioners and the respective anchors. Driven into the ground between said head posts are intermediate posts I arranged in line and evenly spaced apart from each other so as to form a row.
a plurality of wires are fixed to the head posts P and they are generally divided into fixed wires W1 and movable wires W2. Both the fixed and movable wires can be tensioned using the tensioning element 1 of the present invention.
the movable wires are fixed to the head posts using elastically compensating elements 100.
the tensioning element of the invention allows to adjust - in a differentiated manner - the tension of the wires so as to compensate especially the extension changes that the two wires are easily subjected to when handled from the two opposite sides of the row when handling the vegetation.
the differentiated adjustment avoids or readily corrects the inclinations of the tensioning element from the optimal transverse position with respect to the rectilinear direction of the wires. As a result, also the elastically compensating element is kept straight so that it works in the best conditions.
a further advantage of the wire tensioning element of the invention lies in the fact that the assembly thereof is significantly simplified, given that a single operator can do so without involving a second operator, as is currently the case with conventional wire tensioners and without using fasteners.
the outer surface may be processed differently from what is shown and described to meet specific needs or particular preferences.
